COMBINED CHAIR AND STEP-LADDER.

, PECIFICATION forming part of Letters Patent No. 347,883, dated August 24, 1886.

Application filed January 28, 1886. Serial No. 100,100. (No model.)

To 66% whom ib-mwg concern:

Be it known that I, ORLO JONATHAN MARsn, a citizen of the United States, residing at Titusville, in the county of Crawford and State of Pennsylvania, have invented a new and useful Improvement in Combined Chairs and Step-Ladders, of which the following isa specification, reference being had to the accompanying drawings.

My invention relates to an improvement in combined chairs and step-ladders; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claim.

In the drawings, Figure l is a side elevation of my invention when used as a chair. Fig. 2 is a-vertical sectional view of the same. Fig. 3 is a perspective view of my invention when used as a step-ladder.

A represents the standards, which form the rear legs of the chair, and the upper ends of which form the sides for the back thereof. A series of steps, B, connect the standardsA on the rear side of the back 0, the said steps and standards forming a ladder, as will be readily understood.

D represents the front legs or standards, which are connected at their upper ends near the upper ends of the standards A by links E, which links are pivoted to the said standards Aand D. A rung, F, connects the standards D near the lower ends thereof, and a similar rung, G, connects the said standards at about their center.

H represents the bottom of the chair, having the rectangular frame I, the rear end of which is pivoted in between the standards A at a suitable distance from the lower ends thereof. The standards D are connected to the frame of the chair-bottom by links K,which links are pivoted at their ends to the chairbottom frame and the standards D.

When my device is in the position shown in Figs. 1 and 2, forming a chair, the bottom rests on the rung G, and is supported in substantially a horizontal position thereby. The connecting-links K extend rearwardly and the links E extend downwardly. WVhile in this position rockers L may be attached to the lower ends of the standards A and D by means of links M, which are pivoted to the said rockers and are secured at their upper ends to the lower ends of the standards by means of setscrews or bolts N, which permit of the rockers being readily detached from the chair-standards, when desired.

\Vhen it is desired to convert the chair into a step-ladder, the rockers are first detached, the front edge of the chair-bottom is raised, and the standards D moved forward and upward until they assume the position shown in Fig. 3. In this position the standards D are nearly vertical, and the standards A are inclined at an angle of about thirty-five degrees.

A combined chair and stepladder thus con-, structed is extremely light, cheap, and sim ards A, and the pivoted links K, connecting the chair-bottom with the standards D, substantially as described.

In testimony that I claim the foregoing as my own Ihave hereto affixed my signature in presence of two witnesses.

ORLO JONATHAN MARSH.
